Chapter 1 Introduction to Product
The installation and wiring of motor soft starter should be
operated only by professional technicians who should read this
manual in detail before installing and wiring.
Do not perform wiring while the motor soft starter is POWER
ON. Be sureto perform this step onlyafter the power is
disconnected. Otherwise, there is the danger of electric shock.
Be sure the motor chosen should be matched with the motor
soft starter. Do follow this manual while perform installing and
wiring.
While wiring, the three-phase input power supply should be
connected to the terminals R, S and T. The output wire of the motor
should be connected to the terminals U, V and W. Otherwise, it may
cause severe damage to the motor soft starter.
Do not install any capacitor between the output terminals U, V
and Wand the motor. Otherwise, it may cause damage to the motor
soft starter.
The electronic elements inside the motor soft starter are very
sensitive to static. Do not touch the appliances on the circuit board
by hand before anti-static measures are taken.
The ground terminal ( G) should be properly, solidly and
separately grounded .
Once the motor soft starter is installed, please cover pigtails
in the input and output ports with insulated sheath or tape.

1 Input Terminals (R, S,T)
Three-phase input power supply should be connected to the input terminals R, S
and T of the motor soft starter after it goes through the circuit breaker. Three-phase
power supply doesnot differ on phase sequence and can be arbitrarily connected.
While wiring, DOconnect three-phase input power supply to the terminals R, S
and T. Otherwise, itmay result in severe damage to the motor soft starter.
It is recommendednot to shutdown the machine by disconnecting the main circuit
power supply orinstall an electromagnetic contactor between the input terminals R,
S, T and the power supply to run or stop the motor soft starter. Do selectRUN or
STOP keys on the operation panel or external control terminals to run or stopthe
motor soft starter.
2 Output Terminals (U, V, W)
The output terminals U, Vand W should be connected to the three-phase motor. If
the motor counterrotates (reverses), just change arbitrarily two phases of U, V and
W.
Do not installa capacitor orsurge absorber betweenthe output terminals U, V, W
and the three-phasemotor. Otherwise,it may result in failure of the motor soft
starter or damageto the devices.
Too long connectingline between the motor and the motor soft starter may result
in overcurrent trip,increase of cutoff current, lowaccuracy of current display of the
motor soft starter. So, it is suggested to use a line not exceeding 50m.
3) Bypass Connection(L21, L22, L23)
The bypass connectionterminals L21, L22and L23 should be connected to the
electromagnetic contactor.No wrong connectionor incorrect phase sequence!
When the startingof the softstarter is finished, the main loop power device (SCR)
will log outand the bypasselectromagnetic contactor willrun simultaneously. At this
time, the motoris brought intonormal service.
4) Ground Terminal ( G)
The ground terminalof motor softstarter should be properly connected to the
ground to avoidelectric shock orfire. The ground wire cannot share a ground point
with any otherstrong current load.They must be connected respectively, and the
ground wire isthe shorter thebetter

Chapter 4 Operation
4.1 Check beforeoperation.
The following stepsshould be inspected and confirmed beforethe soft starteris put
into operation:
Be sure thatthe application ambient and the inputpower supply complywith the
requirements in thismanual.
Be sure thatthe main circuit is properly wired:The input powersupply must be
connected to theterminals R, S and T; theoutput terminals U, V and W must be
connected to themotor; the bypass electromagnetic contactor isinstalled and properly
connected; the groundterminal is reliably and properly grounded.
Be sure thereis no short cutting or shortto ground ofall terminals and electrified
parts. Allterminals, connectors and screws are tightlyfastened.
4.2 Operation
Now start atrial operation after all the inspection steps in 4.1have been done. While in
trial operation, itis suggested that the motor has vacant load. Ifeverything is OK, then
perform on-load running.
Be careful toselect an optimum mode of operation in accordance withspecific
operational requirements. Seethe detail below:
The factory defaultsetting of theproduct operation mode is operation panel control.
The value ofrated power currentPC should be set to the same as theone on the
motor's specifications label.
Press to startthe motor and press to endit.
Be sure themotor has a smooth running without whistler or vibration.
If the motorstarting is not good enough, just change settings ofthe basic functions
of P1.
If the motor'sstarting torque is not powerful enough, just change theinception
voltage code P0(indicating voltage mode enabled) or the current-limiting value code
P3 (indicating currentmode enabled) to raise the torque.
Be sure themotor rotates in the correct direction.
Only after makingsure there is no anomaly,can the motor be put into formal operation.
Notes:
1) If thereis any anomaly of the soft starter or themotor, or there is adisplay of the
fault code F XX, juststop operation immediatelyand deal withit in accordance with
the protective requirementsin Chapter 6.
2) If theon-spot ambient temperature is lower than -10 , please restartthe machine

Chapter 5 Description of Function Parameters
5.2 Detailed Description of Function Parameters
Functional Code P0 Inception Voltage Setting Range:30~70% Factory DefaultSetting: 30%
Functional description: Thisfunction is used to set thevoltage value of motor soft starter when
it is beingstarted.
Note: Voltage ramp modeis enabled; Set the code P7to "1", thevalue can be modified; Set P7 to
"0",. the inceptionvoltage will be40%.
Functional Code P1 Soft Starting Time Setting Range:2~60S Factory Default Setting: 16S
Functional description: Thisfunction is used to set thetime spent by the motor from inception
voltage to ratedvoltage.
Note: Voltage ramp modeis enabled; Set the code P7to "1", thevalue can be modified.
Functional Code P2 Soft Stop Time Setting Range: 0~60S Factory Default Setting: 00
Functional description: Thisfunction is usedto set the time spent by the motor from
being just stoppedat rated speed to full stop.Set this valueto "0", there is a free stop.
Note: There aretwo stop modesfor motor soft starter: soft stop and free stop.If the
machine has anone-to-multi system, then set the valueto "0".
1 Soft Stop
If the codeP2 is not set to "0",then soft stopmode is selected. The figure belowis the
output current waveform inthe mode ofsoft stop. Underthis condition, the motor is
powered by athyristor shifted from a bypass contactorto a softstarter; the output
voltage of thissoft starter gradually decreasedfrom full voltage till it stops completely,
thus the motordecelerates smoothly and mechanicaloscillation can be avoided. The
output cut-off voltageof soft stopis equal to the Inception Voltage.
In the modeof soft stop, surf of waterpump loads canbe reduced or even removed,
and large currentimpulse caused bysoft stop can be reduced. Thecurrent limitation
value of softstop is a percentage reckoned on thestarting current-limiting value.
Chapter 5 Description of Function Parameters
2 Free Stop
If the codeP2 is set to "0", thenfree stop modeis selected.
In this stopmode, once stop command is received,the soft starterwill disconnect the
bypass contactor anddisable voltage output of the thyristor. Then themotor will
gradually shutdown dueto load inertia. To avoid open phaseerror report, P2should be
set to thismode if the soft starter adoptsone-to-multi wiring method.
Toextend the servicelife of soft starter, free stop mode isgenerally preferred ifthere
is no needto adopt soft stop mode. Infree stop mode,instantaneous output is
completely disabled, thusinstantaneous impulse of heavy current canbe avoided. ZJR1
series of softstarters provide 6 working modes applicableto various kindsof motors
and loads. Sousers should choose a proper oneaccording to different applications.
Functional Code P3 Starting Limitation Current Setting Range: 50~500%Default Setting: 400%
Functional description: Thisfunction is usedto set the peak output currentvalue of a
motor soft starterwhen it is starting. The formulais: set value motor rated current
(Function PC)= peakcurrent (unit: A) that islimited by a motor softer starter to be output.
Note: Current limitingmode enabled; If the code P7is set to "0", the modification will be
valid; If P7is set to "1", the currentlimiting value willbe 400%.
Functional Code P4 Max. Working Current Setting Range: 50~200% Default Setting: 100%
Functional description: Maximumworking current refers to maximum current
performing sustainable operationwhose value is reckoned on thebasis of theset
value in thefunctional code PC. If the currentexceeds the maxvalue, there will be an
inverse-time thermal reliefprotection.
Note: Modification willbe valid if the code P7is set to"0".
Functional Code P5 Undervoltage Protection Setting Range: 60~90% Default Setting: 80%
Functional description: Whenthe actual workingvoltage is lowerthan the set
value, then protectionfor motor soft starter is disabled and the LEDdisplay F09.
Functional Code P6 Overvoltage Protection Setting Range: 100~130% Default Setting: 120%
Functional description: Whenthe actual workingvoltage is higherthan the set
value, then protectionfor the motor soft starter is disabled and theLED display F10.
Functional Code P7 Starting Mode Setting Range: 00~05 Default Setting: 01
1) Current-limiting Start
If the codeP7 is set to "0" (indicatingcurrent limiting), thencurrent starting
mode is selected.The figure belowis a current change waveform of a motor inthe
mode of current-limitingstart. "l1" in the figure refersto the setvalue of starting
current-limiting. When themotor starts, theoutput voltage will rise rapidly tillthe
motor current reachesthe set current-limiting value "l1" and

Chapter 5 Description of Function Parameters
will not goup any more. Then, with gradualraise of output value, the motorwill
accelerate gradually.When the motorspeed reaches the rated speed ofrotation, the
bypass contactor willattract (kick on) and the output current will godown rapidly to the
motor rated current"le" or below. Thus thestarting process is finished.
Even if themotor has a light load or the set valueof current-limiting is big, there is
still the possibilitythat the maximum current of the motor during startcan not reach the
set value ofcurrent-limiting. Current-limiting start mode is usually applied on the
occasion where strictlimitation of current is required.
2) Voltage Ramp Start
When the code P7 is set to "1"(voltage), then voltagestart mode is selected. The figure
below is awaveform of output voltage during voltage limiting ramp start.U1 in the figure is
the starting inceptionvoltage. When the motor isstarted and itscurrent does not excess
400% of itsrated value, the output voltage of soft starter willjump up to U1, then the output
voltage will risegradually as the set starting parameter, and themotor will accelerate with
voltage rise. When the voltage reaches the ratedvoltage Ue, themotor will run at rated
rotation speed andthe bypass contactor will pickup, thus the start-up procedurewill be
completed.
Starting Time:T is the control parameter derived by standard load under standard
experimental conditions, basedon which the soft starter is able to acceleratethe motor
smoothly to completestarting process through the control over output voltage butnot
through the mechanicalcontrol over time (t) regardless of whether the motoris accelerated
steadily. Therefore, if thereis a light load, the starting time will tendto be lessthan the set
starting time. Itis normal if the machine can be started smoothly. Generally speaking,
voltage ramp startmode is applicable to the occasion where there isno strict requirement on
starting current buta high requirement on the stability of starting.
Chapter 5 Description of Function Parameters
3) Kick Start
When the code P7 is set to "2"(kick + current-limiting) or "3" (kick + voltage),then
kick start modeis selected. The figure belowis the change waveform of output in kick
start mode. This start mode can be selectedin case there is a failure start of themotor
due to influenceof the machine's static friction force on theoccasion of heavy loads.
While the machineis just started, DO feed afixed higher voltage to the motor and keep
it for ashort period of time so asto smooth awaystatic friction force of motorloads and
enable the motorrotate, and then select a startmode of current-limiting or voltage
ramp.
Before selecting this mode, it is strongly recommended to startthe motor bynon-
kick starting. Then select this mode ONLYAFTER the motorfailed to start.DO keep
clear of kickstart as possible to reduce unnecessary impulse ofstrong current.
4) Current RampStart
When the codeP7 is setto "4" (current ramp), then currentramp start modeis selected.
The figure belowis a waveform of output currentin the modeof current ramp start. "l1"
in this figurestands for current-limiting value set bythe code P3,and T1 standsfor time
set by thecode P1.
Current ramp startmode is applicable to bipolar motorowing to its strong
accelerating capacity.This mode canalso shorten thestarting period of time within a
certain range.

This working mode is used in an immediatestate and therelay acts at the moment
when the stateset by Pb just begins. The reset momentof this output will be completed1
second s later afterthis state ends up. Eg.: The factory defaultsetting value ofPb is 7,
which means thesoft starter is in a hold mode when energized and therelay attracts
at the sametime. If the soft starter receivesstart command atthis moment, then the relay
will be disconnected.
Programmable sequential output mode takes the whole processof a startas its control
cycle. If themotor is restarted, the previous programmingoutput will automaticallybe
interrupted and thisprocedure shall be preceded again.
If Pb isset to 5~9, the programmable outputworking and stateoutput mode, and the
set working stateoutput will be shown in thetable below:

Programmable state output is used to indicate theworking state ofsoft starter. The
factory default setting value of Pb is 7,which indicates holdmode of softer starter. In
this state, themotor can be started. When programmable output isin fault state, it
indicates motor failure (-F05, -F06, -F07, -F08, -F12), which is different from the
function of failureoutput terminals. Operation state refersto non-hold or non-fault
state, including suchthree procedures as start, bypass andsoft stop.
If Pb>9, thereset state of programmable output ( external terminals) changes
from open toclose, that is, reversed phase output.Flexible use ofprogrammable relay
output functions cansimplify external control logic circuit.

5) Voltage and Current-limitingDouble-closed Loop Start
When the codeP7 is setto "5" (double closed-loop), then thisstart mode is
selected. Voltage and current-limitingdouble-closed loop startmode, with
adoption of voltageramp and current-limiting double-closed loop control,is a kind
of comprehensive startmode that both steady start andstrict current-limiting are
required. It usesa pre-reckoning method for estimating theworking state of the
motor.
The waveform ofoutput voltage inthis mode always fluctuates according to
different conditions ofthe motor andloads.
Functional Code P8 Protective Class SettingRange: 00~04 FactoryDefault Setting: 04
To adaptto different applications,this motor softstarter provides 5 protection classes,
namely, 0:primary class; 1:light load; 2: standard, 3 heavyload; 4: advanced,which
are set bythe code P8.
Primary protection, disablingthe function ofexternal instantaneous terminalsand only
remaining overheat protection,shortcut protection andinput open phaseprotection
while starting, isapplied to some emergency occasions, i.e.,fire pump etc..
Light load, standardand heavy load protection classes havefull protection functions.

Chapter 5 Description of Function Parameters
Functional Code PC Motor Rated Current Setting Range: 11~1200
Factory Default Setting:Set according to the specifications
Function Description: Thisparameter should beset in conformity with rated current
value displayed onspecifications label of the motor.Otherwise, it may cause big
deviation between startingcurrent and protective current. The motorrated current
set by PCshould not be 20% lower thanthe nominal currentof soft starter. The
flexibility tolerance ofprotective trip action will increase ifthere is less motor rated
current set byPC.
Functional Code Pd Motor Protection Setting Range: 00~90 Factory Default Setting: 00
1) Descriptions ofProtective Functions
This motor softstarter has perfect protective functions toguarantee safety whileusing
soft starter andmotor. Whilein use, DO set proper protectionclasses and protection
parameters according todifferent circumstances.
Soft Starter OverheatProtection: Overheat protection enabled when temperaturerises
to 90 5 and disabled whentemperature falls to 60 (lowest).
Input open phaseprotection lag time: <3S
Output open phaseprotection lag time: <3S
Three-phase Unbalance ProtectionTime: <3S. Based on therule that all phases of
current deviation islarger than 50 10%, when loadcurrent is 30% lower than the
nominal rated valueof softer starter, the decisiondatum deviation will be enhanced.
Overcurrent Starting ProtectionTime: Thisrefers to the protection time thatis
successively 5 timeslonger than the maximum working currentset by thecode P4. See
protection TimeTable in Page 23.
Overload Running ProtectionTime: Thisrefers to the inverse time thermalrelief
protection based onthe maximum working current set bythe code P4.See the curve of
trip protection timein the figure on page 26.
Power Supply UndervoltageProtection Lag Time: When powersupply voltage is40%
lower than limitvalue, the protection time will beless than 0.5second; when the
power supply voltageis lower than the set value,the protection timewill be less than 3
seconds.
Power Supply OvervoltageProtection Lag Time: When powersupply voltage is130%
higher than limitvalue, the protection time will beless than 0.5second; when the
power supply voltageis higher than the set value,the protection timewill be less than
3 seconds.
Load Shortcut ProtectionRetarding Time: <01 second. Ifthe current is 10 times or
more as nominalrated current of the soft starter, than afuse or shortcut device shall be
used.
The above timeparameters are set for the periodfrom valid signalsare detected to trip
protection command isgiven. They arefor reference only.
If protective functionsof this soft starter do notcomply with users needs, then
special protective devicesshall be used to insure safety.
